A further object of the invention is to provide a tong of the above described character wherein manipulation of a single member will enable the user to obtain the desired ad- Vustment of the jaw for theV purpose desired.

Other objects and advantages of the present invention will become apparent as the description of the same proceeds and the invention will be best understood from a detailed description of the accompanying drawing forming a part of the present invention, 'with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing but may be changed or modified so long as f such changes or modifications mark no material departure from the salient features ofthe 0 invention 'as expressed in the appended claim. In the drawing: Y Y Figure 1 shows the tong embodying the present invention, in side elevation.

` Figure 3 is a sectional view taken substantially upon the line 3-3 of lFigure 2.

Figure 4 is a section taken transversely ofv 4 the shiftable element` of one jaw,v removed from position. i

Referring now to the :drawing in detail wherein like numerals of reference indicate corresponding parts throughout the severall views, the tongs comprises the handlemembers 1 and 2 which are arranged in crossed relation and secured in relative movable relation by the screwy 3. Y

Each of the handle members 1 and 2 foro wardly of the pivotal point is formed to-.provvide a pairof elongated jaw members indicatedras a whole by the-numeralsf4and 5j.
